Single Unmibical Artery (SUA) at 20 week ultra sound

I just found out yesterday that the baby's umbical cord only has two of the three vessels. His heart and kidneys seem to be fine at this moment. But it all seems like a waiting game. Ezra and I have been perfect up until this point. Have any of you been through this experience?

Thanks!!! I love hearing about all of the good outcomes!! Googling it was not the best idea I have had! But I guess it does open my eyes to what could happen. I am just trying to stay positive for both of us❤️. My first pregnancy 3 years ago was with twin boys who went full term without any issues and I felt like this pregnancy was perfect. So it did shake me completely.
